MOFs as adsorbents for low temperature heating and cooling applications.

Abstract: The 3D metal−organic framework (MOF) 3∞{[Ni3(μ3-btc)2(μ4-btre)2(μ-H2O)2]·∼22H2O} is found to be a reversibly dehydratable−hydratable water-stable MOF material with a large loading spread of 210 g/kg as a candidate for solid adsorbents in heat transformation cycles for refrigeration, heat pumping, and heat storage.

Method for producing an adsorbent from organometallic framework structures (mof)

Abstract: The present invention relates to a method for the production of an absorbent made of metal-organic framework structures (MOF), in the case of which at least one metal salt is converted with at least one organic ligand. The conversion is effected at a temperature greater than 100° C. in a solvent mixture which comprises DMSO and water. The invention relates in addition to an adsorbent produced with the method according to the invention or to a substrate coated with such an adsorbent and also to possibilities of use of such an adsorbent or substrate.

Method for coating a heat exchanger structure, coated heat exchanger structure and use thereof

Abstract: The invention relates to a method for coating a heat exchanger structure, in which a porous sorbent is applied together with a binder to a support structure and is filmed and/or crosslinked to form a layer. The invention likewise relates to heat exchanger structures coated in this way. The heat exchanger structures of the invention can be used in heat pumps, heat stores or refrigeration machines and also in sorptively assisted air-conditioning systems.

Dispersion, method for coating objects with this dispersion, and use of the dispersion

Abstract: The invention relates to a dispersion and a method for coating objects, in particular heat-exchanger structures, in which this dispersion is applied to a support structure and is crosslinked and/or formed into a film, forming a layer. The invention likewise relates to heat-exchanger structures coated in this manner. The dispersions according to the invention can likewise be used for coatings in chemical installations construction and also in medical technology.

Chemical, thermal and mechanical stabilities of metal–organic frameworks

Abstract: The construction of thousands of well-defined, porous, metal–organic framework (MOF) structures, spanning a broad range of topologies and an even broader range of pore sizes and chemical functionalities, has fuelled the exploration of many applications. Accompanying this applied focus has been a recognition of the need to engender MOFs with mechanical, thermal and/or chemical stability. Chemical stability in acidic, basic and neutral aqueous solutions is important. Advances over recent years have made it possible to design MOFs that possess different combinations of mechanical, thermal and chemical stability. Here, we review these advances and the associated design principles and synthesis strategies. We focus on how these advances may render MOFs effective as heterogeneous catalysts, both in chemically harsh condensed phases and in thermally challenging conditions relevant to gas-phase reactions. Finally, we briefly discuss future directions of study for the production of highly stable MOFs. Metal–organic frameworks (MOFs) have shown promise in a broad range of applications, including catalysis. In this Review, the chemical, thermal and mechanical stabilities of MOFs, in particular with catalytic uses in mind, are discussed.

Water adsorption in MOFs: fundamentals and applications

Abstract: This review article presents the fundamental and practical aspects of water adsorption in Metal–Organic Frameworks (MOFs). The state of the art of MOF stability in water, a crucial issue to many applications in which MOFs are promising candidates, is discussed here. Stability in both gaseous (such as humid gases) and aqueous media is considered. By considering a non-exhaustive yet representative set of MOFs, the different mechanisms of water adsorption in this class of materials are presented: reversible and continuous pore filling, irreversible and discontinuous pore filling through capillary condensation, and irreversibility arising from the flexibility and possible structural modifications of the host material. Water adsorption properties of more than 60 MOF samples are reported. The applications of MOFs as materials for heat-pumps and adsorbent-based chillers and proton conductors are also reviewed. Some directions for future work are suggested as concluding remarks.

Abstract: This review (over 380 references) summarizes metal–organic frameworks (MOFs), Materials Institute Lavoisier (MILs), iso-reticular metal–organic frameworks (IR-MOFs), porous coordination networks (PCNs), zeolitic metal–organic frameworks (ZMOFs) and porous coordination polymers (PCPs) with selected examples of their structures, concepts for linkers, syntheses, post-synthesis modifications, metal nanoparticle formations in MOFs, porosity and zeolitic behavior for applications in gas storage for hydrogen, carbon dioxide, methane and applications in conductivity, luminescence and catalysis.

Adsorptive separation on metal-organic frameworks in the liquid phase.

Abstract: While much attention of the MOF community has been devoted to adsorption and purification of gases, there is now also a vast body of data on the capability of MOFs to separate and purify liquid mixtures. Initial studies focused on separation of petrochemicals in apolar backgrounds, but the attention has moved now to the separation of complex, e.g. chiral compounds, and to the isolation of biobased compounds from aqueous media. We here give an overview of most of the existing literature, with an accent on separation mechanisms and structure–selectivity relationships.
